If you've ever closed a Claude Code session and immediately forgotten what you just figured out — this one's for you.
ACE stands for Alpha Charlie Echo or (All Clear Exit). You say it at the end of a session, Claude generates a structured summary, and it saves automatically to your session library. Accomplishments, key decisions, lessons learned, what's blocked, what's next.
One phrase. Every session. Searchable forever.
The lesson is 40 minutes, 9 blocks, hands-on. By the end you'll have your session library set up and your first ACE summary saved.
It's live in the classroom now.
